Just one question: many of my vinyl are more than 30-40 years old and its shape isn't mint in terms of what we're grading as totally unused/unplayed record. Even if I am keeping them all in separate plastic covers, many titles have covers that have minor or slight wear on spines or edges and I am worrying that these issues may progresses within a time.

Do you have any special treatments to protect your vinyl covers from further damage? Is there any chemical substance that can glue thin paper on cover or preserve it from any kind of damage (similar to of what people do to to the old books)? Most of vinyls are still in an great shape and I don't wanna see them more shabby.
